result in a cumming action between the o eratingt, portion 22 of thc lever 20 and t e abutment portion 26 of the stationarily mounted bracket 13, resulting lin the opening movement of the door 11. When the door 11 is open and it is desired to move said,y door to closed position, the final s ta es of above referred to.

v The present invention contemplates the provision of certain improvements over said Creer patent, whereby the car door mayfbe el'ectually sealed against surreptitious opent has been common practice to provide ahasp fastener, a ha'sp iz'isteningstrap and locking bolt. One of the trickstowhich car thieves have resorted has been to saw through the material providing the vbottom part of the'slot in the locking bolt in which the car seal is mounted, enabling said" thief to open the car door -without breaking the seal and, after he has left the car, putting the parts back in the positions in which he found them, the saw cut being quite inconspicuous and very likely to be overlooked by the car inspectors. Among the objects of the present invention is the object of providing a structure which will eii'ectually prevent any such procedure on the part of a car thief.

Slidably mounted upon the pin'16 is the locking'bolt 27, which locking bolt is adapted to reciprocate in an aperture 28 rovided by the-bracket 13'. Formed integra. ly with the lever 20 isthe hook member 29 having the hooked-over end portion 30. The lower eX- tremity-of the locking bolt 27 is adapted to occupy a position in obstructing relationship with the hooked-over end portion 30 of the hook member 29. That is to say,when the door is in closed position and the lever 20 is moved to thelimit vof its movement in a clockwise direction, the hooked-over end portion 30 of the hook member.29 will be disposed in such a position that when the locking-bolt 27 is in its lower-most position, said locking bolt 27 will effectually prevent the opening movement of the door 11 by reason of its obstructing relationship with said hooked-over end portion 30. The bracket 13 is provided with a portion 31 underlying i thelower extremityof the locking bolt 27,

though providing an opening 32 for permitting ingress and egress of the hooked-over end portion 30 of the hook member 29 of the lever 20. The lower extremity of the locking bolt 27 is provided with the slot 33,

arts areviewed in Figures 1 and 2, will monly provided for sealing freight car doors.

Inasmuch as the locking bolt 27 is adapted to have a swinging movement about the pin 16, it is a simple matter to hold locknfr bolt 27 up out of its operative osition, as s iown Vin Figure 2. lVilh the loc ing bolt 27 in inoperative position, no interference is had with the opening and closing of the cur door.

According to the embodiment of the present invention shown in Figures 6 and 7, the hook member 29 has not only a hooked-over end portion 3() but has the hooked-over end portion 35 adapted to cooperate with the ownwardly extending lock 36 forming part of the bracketv 13. The portions 35 and 36 of the hook member' 29 and the bracket 13, respectively, will cause the door to lock auto- Vmatically when said door is moved to closed position and the lever 20 is moved in a clockwise direction.. By reason of this construction the door 11 will be held closed when the car is being shunted about, even though the locking bolt 27 is not disposed in its locking position.

rlhe present invention presents the advantage that the portion 31 of the bracket 13 will protect the lower extremity of the locking bolt 27 against attack by thieves. For this purpose the bracket 13 may be of tool resisting steel. 'Whether or not the portion 31 of the bracket 13 is of tool resisting steel, it will be a practical impossibility for a thief to saw through said portion 31, due to the proximity o? the lever 20. It will therefore be impossible for a thief, when the locking bolt is in operative position,`to saw through the lower extremity of the locking bolt 27 to permit the raising of said locking bolt without breaking the seal.

As indicated above, all the nuts ai'e presented to the inside of the car, whereby to burglar-proof the entire arrangement. The construction is simple and sturil and may be readily made of forgings, wiercby great strength and relatively light Weight are had.

Though a preferred embodiment of the present invention has been described in detail, many modifications will occur to those skilled in the art. It is intended to cover all such modifications that fall within the scope of the appended claims.

lVhat is claimed is:

1. In a railway car, in combination, a relatively stationary frame member, a relatively movable door member, means for forcing said door to closed position and for holding said door in closed position, said means including a reciprocable bolt upon one of said members and a lever upon the other of said members, and means upon said frame member constituting an abutment for said ,hun

lll

' said frame member, a lever upon said oor` bolt, said abutment means and said bolt having apertures adapted to coincide with one another' for the reception of a sealing membei', said abutment means includin a portion underlying said bolt and having protective relationship with said bolt to prevent the sawing of said bolt to remove said sealing member.

member, a unitary mounting means u on member, said mounting member having mounted thereon a member for cooperation with said lever for forcing said door to closed osition, a reoiprocable bolt carried by sai mounting means, said bolt being adapted to be moved into abutting relationsliip with vsaid mounting means and said lever for holding said door in closed position, and an abutment portion having co4 operating apertures for the reception of a sealin member said abutment ortion com` prising a portion "for protecting the extremity of saidplocking'bolt toy prevent the disengagement of said `locking bolt and said sealing member.

3; In a railway` car, in combination, a relatively stationary frame member, a relatively movable door member, unitaryl mounting means iiponone of' said members and a lever upon the other of said members, means carried by saidI mounting member for co 'ventin operation with said lever for moving said door to closed position,

ating with said mounting member and said lever for preventing the opening of said door, said mountin member and said bolt cooperating aperturesw Y l for the reeepti n of a sealing member, said 2. In combination, a vrelatively stationary `iiame member, a relatively movable door being provided Wit mountingv mem er being also provided with a portion for protecting the extremity of said bolt'against surreptitious attack.

4. Inv a railway-car, in combination, a 45 relatively stationary Jframe member, a rela tively movable door member, unitary mount ing means upon one of said members and a lever upon the other of said members, means carried by said mounting member for operation with said lever or movin said door to closed position, and a longitu inally reciprocable bolt for cooperating with said mounting memberand said lever for pre mounting member and said bolt bein provided With cooperating apertures for t "o re# ceptionof asealing member, said nimmt@V ing member being also provided with a pore tion for bolt against surreptitious attack.
